guide face; ah lower 'gi ide mm l {illmiilifi lflw' QQ-V of that wh Figs. 1, 2- anfl 3. Having reference more particularly to Figs. 2 and 3, the disk 13 is shown 'thoroin' fu nished with a peripheral flange or rim 131 outside the pad-body l4, and the said disk is held to the stem 12 ill a manner permitting the same to turn relative to the said stem. In Fig. 2, 132 is a holding screw having a flanged head and an enlarged plain body-portion next to the I v i said head. The disk is formed with a central hole fitting the said enlarged plain bodyqaortion. 'lhe' threaded portion of the screw is screwed into .a threaded. hole which is tapped in the lower end ofvthe steurlznnd the shoulder which is formed by the eiilarged'v plain body-portion of the screw makes contact with the lower end of thestem 12. This mode of connection leaves the disk free to turn upon the en- 'largedmlain bodyortion of the screw.

The stenbl2 is externa ly'screw-threa ded, and

'to the said stem is applied the internallythi eall'ed hub or out 193, which latter is jconnected the arms 134,- 134, with the clamping ring 135. "ETheJatter occupies a position. below the flange or rim 131- of the disk '13. The marginal portion of the cheese-cloth covering i's-jntrodu'ced between the. said flange or rin'i, (if the disk and the clamping ring, and then, after thesaid cloth astoscrew the hub f'of the clam in upwards-long the aitid stema'n cause the said ringtealamp the cloth against the flange or rim 131'of has been properly strained around the bodyofthe .pad, th' pad, disk, and clamping ring are rotat '.-relative to the stem 12 so "the" margin of the disk 13. I 'The polisher is furnished with .a handle,

- as 18, Fig. 1, by which it may be held by the work-person and moved into any position that may be necessary in working upon the upper or cap of a shoe. The polisher' .is' small and light, and therefore easily port- 'able manually, and in using the same its pad may be caused to bear with any required degree of pressure upon the placetobe polished, and also as lightly and delicately as may be desired;

To enable the polisher to be moved about working u freelyby the work-person around a shoe which is bemg operated u on, and caused to assumeall fpofitio'ns whic may be necessary in n such shoe, the actuating connections or the crank-shaft 9 include a length of flexible shafting, the exterior caswith the crank-shaft 9. The. other on of the same is coupled with the driving-shaft 1. The said drivin -shaft-i s journaled 1n fixed bearings whic are rovided at 21, 21, u on a stand 22. It is mished 1 wi h a fast and-pulley, 23, and a loose band,-

pulley 24 to which band-pulleys-. i s ap-- plied pi'actice a suitable actuating .driv- ,0 the n t ereby therewith, the said of which'is, shown at 19,- 1.,. Que; of'the said flexible shafting'fis c'ou led mama in -band not shown. I To prevent breakage flexible shafting, or the couplin whereby it is connected with the driving-she t v 20, 1n consequence of the flexible shafting being bent, too sha'fply closely adjacent the oint oficonne'ction with the driving-shaft, provide a guard device or restramer, 25

which is shown in' Figs. 1 and 4, and which is in the form of a ring or shell, th'rou h the opening 26, Fi 4, of which the flexib e v shaftmg passes. he said guard-device or restrainer is located at a convenient distance furnished with a su porting-stand 27. The wall of the guardevice or restrainer enlarges or flares in bell-shape in thedirection from the point of connection -.aforesaid to-- wardthe polisher, so as to provide for a radual change in the directionof the flexle shafting when it is bent transversely around the said wall. 7 To further reduce the tendency tobreakage of the flexible gshafting in cons uence of bending thereof,

I provide for. a si ht amount ofend play from the said point of connection, and-is;

of the driving-she t 20. in its bearings '21,

21, as indicated in Fig. 181) the space existmg at; the left of the pu gay 23, betwceh suchpulley and the ad oining bearing 21;

This opportunity for end-play enables the 1 driving-shaft to. move in the direction of its length whenthe flexible shaft is; bent or curved.

At 28 is a' c lindrieal brush which is car ried by the driving-shaft 20 and-rotates rush being intended to be used in clearin away dust, etc, after the scouring opera ion, preliminary to the application of the composition or preparation aforesaid, and for other In practice, thejdrivingaft is rotated at a considerable number of turns per minute, producing a rapid reciprocating movement of the polishing ad. At the place ted the surfacing material is completely scoured ofi down tothe where a crack is loca leather itsel after-which the composition or reparation is applied.
